i have an apple tv, sky q box and sony bluray player connected to a sony str d1080 amp, with output to a Benq projector. Blu-ray video and audio output are working fine. however i am getting degraded video images/ spiking on the videowhen using either the apple tv or the sky q box (audio is not affected).Ive done some basic problem solving like changing HDMI cables and switching inputs from the apple tv and sky q box  to the bluray input but no improvement. Can anyone help diagnose the issue? could it be a setting issue with the amp or with the apple tv and skyq box or video  signal incompatibility?
